Unless you have extra $$$ laying around, Steve Jobs is a bit of a bad example of justifying a Porsche.
They simply are not cheap cars to keep running reliably
Everything that makes them go tends to be more expensive than the more typical car a 17 year old would own.
Also there is no going to Pep Boys to pick up parts. Most every part I have needed I had to order online and wait. So If something goes wrong it may be several days/weeks before you get it back on the road

Most 17 year olds (myself included) their first car is their learning car. So sometimes that learning curve means doing things a couple times. Some of the fixes on my Boxster pushed me to the limit after one time (AOS, Expansion tank).

These are old cars, old cars need upkeep. Boxsters selling price is very attractive.
BUT - Old German Sports cars and their up keep is not cheap. If you can handle the financial part then go for it
